Cell Theory

The theory is one of the major theories in science because it tells the most important description of a cell. It is also very important because it was not observations of one person, but many scientists. Some of them were Schleidan, Schwann, and Virchow.
The cell theory is…
1. All organisms are made up of cells.
2. Cells are the basic unit of structure and function in all organisms.
3. All cells come from cells that already exist.
